Sun visor

ABSTRACT

A sun visor includes two head band portions extended from a central visor portion and each having one or more coupling members to couple the head band portions together and to form a head encircling device and to adjustably attach the sun visor onto a head of a user. Two or more folding lines are formed between the center visor portion and each of the head band portions, and inclined relative to each other, to form a superposed portion between the center visor portion and the head band portions after the head band portions are folded relative to the center visor portion along the folding lines, and to form a frustum-shaped structure, but not a cylindrical-shaped structure for the head encircling device.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a sun visor, and more particularly to asun visor having two folded head bands to form a frustum-shaped headencircling device, and to comfortably and firmly attach the sun visoronto heads of users.

2. Description of the Prior Art

Various kinds of typical sun visors have been developed and include ahead covering or cap provided for attaching onto heads of users.

For example, U.S. Pat. No. 1,718,867 to Mahlmann discloses one of thetypical sun visors comprising a head covering or cap provided forattaching onto the heads of the users, and an eye shade attached to thehead covering or cap for shielding eyes from sun shines. However, thehead covering or cap is made of open mesh fabric and may not be easilymade by users themselves.

U.S. Pat. No. 4,262,367 to Herrin discloses another typical sun visorcomprising an elastic string having one end attached to a visor portion,and a retainer attached to the other end thereof, for engaging with thevisor portion, and for attaching the sun visor onto the heads of theusers. The elastic string should be made of resilient or elastomericmaterials that is different from that of the visor portion.

U.S. Pat. No. 4,556,993 to Okamura, Sr. discloses a further typical sunvisor comprising a head encircling band attached to a visor, forattaching the sun visor onto the heads of the users. The head encirclingband should also be made of resilient materials that is different fromthat of the visor portion.

U.S. Pat. No. 4,670,910 to Rosasco discloses a still further typical sunvisor comprising two head band portions extended from a center portionand having slits engageable with each other to provide an adjustable fitto the users' head size. However, the head band portions are directlyextended from the center portion and sun visor and may form acylindrical structure that may not be suitably or comfortably attachedonto the heads of the users.

U.S. Pat. No. 5,010,590 to Haber et al. discloses a still furthertypical sun visor also comprising two head band portions extended from acenter bill portion and having notched ends engageable with each otherto provide an adjustable fit to the users' head size. However,similarly, the head band portions are directly extended from the centerbill portion and may also form a cylindrical structure that may not besuitably or comfortably attached onto the heads of the users.

The present invention has arisen to mitigate and/or obviate theafore-described disadvantages of the conventional sun visors.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1-6, a sun visor 10 inaccordance with the present invention comprises a central visor portion11, and two head band portions 12, 13 extended perpendicularly from thecentral visor portion 11 and each having one or more catches or slots orcoupling members 14 formed therein and engageable with each other, tocouple the two head band portions 12, 13 together and to form a headencircling means or device 15 for adjustably attaching the sun visor 10onto the heads of the users.

Two or more folding lines 16, 17 are provided or formed between thecenter visor portion 11 and each of the head band portions 12, 13, andare inclined relative to each other. For example, the head band portions12, 13 may first be folded relative to the center visor portion 11 alongthe folding line 17 (FIG. 4), and then folded along the other foldingline 16 (FIG. 5), to form a folded and/or superposed portion 18 betweenthe center visor portion 11 and each of the head band portions 12, 13.

Alternatively, the head band portions 12, 13 may first be foldedrelative to the center visor portion 11 along the folding line 16 andthen folded along the other folding line 17, to form the folded and/orsuperposed portion 18 between the center visor portion 11 and each ofthe head band portions 12, 13.

After the head band portions 12, 13 are folded relative to the centervisor portion 11 along the folding lines 16, 17 to form the foldedand/or superposed portion 18 between the center visor portion 11 and therespective head band portions 12, 13, and due to the inclination of thetwo folding lines 16, 17 relative to each other, a head encirclingdevice 15 may be formed (FIGS. 1, 2, 6) and may include a frustum-shapedopening 20, but not a cylindrical-shaped opening, to comfortably andfirmly attach the sun visor 10 onto the heads of the users.

It is preferable that one of the folding lines 16 is perpendicular tothe respective head band portions 12, 13, or perpendicular to thelongitudinal axis 90 (FIG. 3) of the respective head band portions 12,13, and the other folding line 17 is inclined relative to the foldingline 16, or inclined relative to the respective head band portions 12,13, or relative to the longitudinal axis 90 of the respective head bandportions 12, 13, in order to form the frustum-shaped opening 20 of thehead encircling device 15.

As shown in FIG. 3, illustrated is a planar prototype that may bedirectly cut from a planar and/or rectangular sheet member (not shown),with such as cutting dies, for allowing the sun visor to be easily andquickly made in mass production. The planar prototype may then be foldedinto the sun visor 10 along the folding lines 16, 17, and the two headband portions 12, 13 may then be coupled together to form the headencircling device 15 for adjustably attaching the sun visor 10 onto theheads of the users. The folding lines 16, 17 may have one end 19 mergingor contacting or superposed with each other.

Alternatively, as shown in FIGS. 7-12, the head band portions 12, 13 maybe extended from the center visor portion 11 toward differentdirections, and may also include two or more folding lines 16, 17provided or formed between the center visor portion 11 and each of thehead band portions 12, 13, and inclined relative to each other, forforming the frustum-shaped head encircling device 15 after the head bandportions 12, 13 are folded relative to the center visor portion 11 alongthe folding lines 16, 17.

Further alternatively, as shown in FIGS. 13-16, the head band portions12, 13 and the center visor portion 11 may include different shapes orcontours or configurations from that shown in FIGS. 1-12, and may alsoinclude two or more pairs of folding lines 16, 17 provided or formedbetween the center visor portion 11 and each of the head band portions12, 13, and inclined relative to each other, for forming two or morefolded and/or superposed portions 18 between the center visor portion 11and the head band portions 12, 13, and to adjustably fit to the users'head size.

Accordingly, the sun visor in accordance with the present inventionincludes two folded head bands to form a frustum-shaped head encirclingdevice, and to comfortably and firmly attach the sun visor onto heads ofusers.
